When searching for information about the coin you are interested in, you are in addition to the rating Coinmarketcap.com you can also use Coingecko.com. There you will also find information where you can buy the coin you are interested in.
I believe the information on coinmarketcap and Coinecko is only validated coins.
I have another solution if it's really new, but we want to know the token information.
This only applies to BSC network tokens for now, we can paste the smart contart address
at
https://poocoin.app/ then we will get enough information from the smart contract.
To be listed on Coinmarketcap and Coinecko it seems that there are requirements that must be met first,
so I'm sure new tokens will not be listed there quickly.
